mg to Tablets with Maximum Dose Cap
Caps a single dose to a maximum, then converts mg → tablets (orange C1C2 standard)
Calculator
Cap a dose to a maximum, then convert mg → tablets
Educational use only. Verify max dose limits in your local formulary and follow local policy.
How it works
This calculator prevents a calculated dose from exceeding an absolute maximum single-dose safety limit. It first applies the cap, then converts the resulting dose into tablets using the tablet strength.
Always confirm max dose limits in your local formulary/product info and follow local tablet-splitting policy.
Formula
Worked examples
Example 1: Calculated 800 mg, max 1000 mg, strength 400 mg/tablet
Tablets = 800 ÷ 400 = 2 tablets
Example 2: Calculated 1200 mg, max 1000 mg, strength 500 mg/tablet
Tablets = 1000 ÷ 500 = 2 tablets
Example 3: Calculated 300 mg, max 500 mg, strength 250 mg/tablet
Tablets = 300 ÷ 250 = 1.2 tablets
When this is used
- Medications with an absolute maximum single-dose limit
- Paediatric dosing (weight-based) where caps are common
- High-risk meds where overdosing is clinically significant
- Tablet-only scenarios where liquids/alternate strengths may be required
